6937664426 net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall back
Ignore the return value of eth_getenv_enetaddr_by_index(), and if it
fails, fall back to use dev->enetaddr, which could be filled up by
the ethernet device driver:

With the current code, introduced with below commit, eth_write_hwaddr()
will fail immediately if there is no eth<n>addr in the environment variables.

However, e.g. for an overo based product that uses the SMSC911x ethernet
chip (with the MAC address set via EEPROM connected to the SMSC911x chip),
the MAC address is still OK.

On mx28 boards that are depending on the OCOTP bits to set the MAC address
(like the Denx m28 board), the OCOTP bits should be used instead of
failing on the environment variables.

Actually, this was the original behavior, and was later changed by
commit 7616e78508.

4793ee6522 net: tftpput: Add support for receiving ICMP packets
ICMP packets can tell you when there is no server at the other end. It
is useful for tftp to figure this out, so that a quick error can be
displayed, rather than pointlessly retrying.

This adds an ICMP packet handler to the net interface.

6dc809f407 net/dns.c: Fix endian conversion for big-endian in dns command
net/dns.c used endian conversion macros wrongly (shorts in reply
were put swapped into CPU, and then ntohs() was used to swap it
back, which broke on big-endian).

Fix this by using the correct linux conversion macro for reading
a unaligned short in network byte order: get_unaligned_be16()
Thanks to Mike Frysinger pointing at the best macro to use.

Tested on big and little endian qemu boards (mips and versatile)

This is long over due.  All but two net drivers have been converted, but
those have now been dropped.

The only thing left to do is actually delete all references to NET_MULTI
and code that is compiled when that is not defined.  So here we scrub the
core code.

Commit 093498669 (Put common autoload code into auto_load() function)
broke handling of autoload environment variable not being set.
The bootp/dhcp code will just keep on requesting IP address forever
and never start TFTP download.

Fix it by moving TftpStart() outside the conditional like it was before.

7616e78508 Add Ethernet hardware MAC address framework to usbnet
Built-in Ethernet adapters support setting the mac address by means of a
ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr).

This adds similar support to the USB network side, using the names
usbethaddr, usbeth1addr, etc. They are kept separate since we don't want
a USB device taking the MAC address of a built-in device or vice versa.

23a70bf9c3 net/net.c: Update ipaddr if the environment has changed
At least on ARM the ipaddr is only set in board_init_r function. The
problem is if ipaddr is not defined in environment importing another
environment defined don't update the ipaddr value.

For example, suppose we've a default environment without net variables
defined and we want to import an uEnv.txt environment from SD-card like
this:

  ipaddr=192.168.2.240
  netmask=255.255.255.0
  gatewayip=192.168.2.1
  serverip=192.168.2.114

Then if you try boot from NFS results in:

  Importing environment from mmc ...
  Running uenvcmd ...
  smc911x: detected LAN9221 controller
  smc911x: phy initialized
  smc911x: MAC ac🇩🇪48:00:00:00
  *** ERROR: `ipaddr' not set

The ipaddr at this point is NULL beacause is only set at board_init_r
function. This patch updates the ipaddr value if the environment has
changed.
